Britney-Rihanna lock lips on stage!

The Billboard Awards opened with a steamy performance by singing sensations Britney Spears and Rihanna. Both the singers were clad in identically provocative costumes, with buckles, straps and fish-nets, and pants that were conspicuous only by their absence!

Spears and Rihanna were accompanied by topless dancers; their performance saw them sporting masks and included seductive dance steps involving poles, not to mention a pillow fight which ended with feathers flying everywhere. But it was not just the feathers that went flying, for the spectators' heartbeats went flying too when they got to see Britney and Rihanna kissing each other, which bought back memories of the on stage liplock between Britney Spears and Madonna eight years ago.
